Normally I think most things like this are over reactions by anti-gun officials who would rather cry zero tolerance rather than actually think for themselves (for instance during pop tart gate).
However, in this case I am putting the blame firmly where it belongs, on the father.
According to WRAL, A Raleigh, NC father photographed his son on a playground, wearing full camo, a ski mask, and pointing a BB rifle (with no sort of orange tip) directly at a school across the street.
That alone, OK, maybe they wanted to do some weird father/son para-military photo shoot at a playground. OK, I guess (pointing a gun, even a BB gun at a school is certainly never OK though).
